(CNSNews.com) - "Why the hell would I take a test?" a testy Joe Biden asked CBS correspondent Errol Barnett during an interview on Tuesday.
Barnett began his question by noting that Biden, when asked in June if he'd been tested for cognitive decline, said he's "constantly tested."
Barnett asked Biden, "Please clarify specifically, have you taken a cognitive test?"
"No, I haven't taken a test!" Biden responded. "Why the hell would I take a test? C'mon man! That's like saying you -- before you got on this program, you take a test where you’re taking cocaine or not, what do you think? Huh? Are you a junkie?”
(After a pause, Biden, who was annoyed moments earlier, laughed.)
Barnett followed up: "What do you say to President Trump, who brags about his test and makes your mental state an issue for voters?"
"Well, if he can't figure out the difference between an elephant and a lion, I don't know what the hell he's talking about," Biden said.
"Did you watch that -- look, come on man, I know you're trying to goad me, but I mean, I'm so forward looking to have an opportunity to sit with the president or stand with the president at the debates. There's going to be plenty of time. And by the way, as I joked with him -- you know, I shouldn't say it. I'm going to say something I probably shouldn't say.
“Anyway, I am -- I am very willing to let the American public judge my physical and mental fil -- my physical as well as my mental fil -- fitness. And to, you know, make a judgment about who I am."
